What's Wrong?

I have asked Claude to stop using the jargon-heavy and unreadable language at least 50 times. It is in the CLAUDE.md file, in the rules and I mention it in my requests.
It adds it to the notes and memory files and it has confirmed it has multiple notes on the subject.
Still it refuses to follow its own rules.
Basically the memory does not work too well or my Claude is a bit Alzheimer-ish.

What Should Happen?

follow the rules and the CLAUDE.md file.
